from the general contact plane of the band.

As is well known th'e'packing box industry, the ends of theconnn'on hoop iron bands. nailed on packing vboxes to hold the f parts thereof securely together, are usually severed very roughly so that sharp rough corners project in such manner `as to tear the khands or clothing of persons handling the boxes without a great degree of care.

Bands having corrugations extending lengthwise thereof are wellknown in the art; but, heretofore, these bands, when cut into lengths, usually have their ends square and expose the corrugations. in .cross-section in such manner as to present projecting parts which yare likelyto catch on the clothing or yparts ofthe body of persons bound with such bands.

It is the object of the present invention to employ corrugated bands of the type referred t0, `but having the ends thereof severed and shaped in such manner as to avoid the proj ec-l tion of edges above the plane of the surface on which the bands may be nailed.

- Another object of the invention is to provide a machine for severing bands of the corrugated type in such manner ,as to shape the severed ends circularly so asto continue the outer corrugations around the endsl and have all Contact edgesof the bands lying the same plane. v

Other objects of the invention will become apparant as the detailed proceeds. Y

' The bands used in practicing this invention come in long rolls from which the user is ex-y pected to'severwhatever length he may find necessary lin binding packing boxes or simil'arpackages adapted toreceive and hold nails for securing thebands in position.

Vhatever the width of the bands, it is es'-Y sentialthat-their outer edges be .curved downwardlyiinfl the same direction so' as tof form a'central substantiallyflat kpart raised from the plane oftsu'ch edges.

It will be obvious from inspection of the drawings that the lengthwise corrugations or beads on the edges of the bands form stiffening means which prevent the bands buckling, and cause them to lie with their edges 5 and 6 in close contact with the packing box 10. The circular continuation of these beads serves the same purpose and causes the severed ends to lie rigidly in close contact With the packing box, and thereby eliminate all chance of any part of the band catching on the clothing or body of any person handling packing boxes secured by these bands.

As shown in Fig. 5, the bands may have their ends spaced apart from each other or may have these ends overlapped, and in either case will be apparent that there are no projecting parts adapted to catch on the clothing or body of persons handling the box.

The machine for severing the bands and for shaping the severed ends, comprising a base 11 provided with lugs 12 and 13 adapted to be secured to a table or other support by bolts 14 and 15. A standard 16 extends up from the rear of the base 11 and has a plunger 17 mounted to reciprocate in said standard.

The standard 16 is bifurcated at its upper end and the upper part of the plunger 17 reciprocates between the furcations 18 and 19 of the standard 16. A bolt 20 extends through the furcations 18 and 19; and a lever 21, having its lower end bifurcated, is pivoted by means of its furcations 22 and 23 to the bolt 20. The furcations 22 and 23 are cam shaped and have their edges arranged so as to engage a head 24 formed on the upper end of the plunger 17.

Between the head 24 of plunger 17, and an abutment 25 formed on the standard 16 between the furcations 18 and 19, a compression spring 26 is arranged so as to maintain the head 24 in constant contact with the cam edges of the furcations 22 and 23 of lever 21. Normally, the spring 26 holds the plunger 17 in raised position, so that the male die 27 on the lower end of plunger 17 is normally separated from the female dies 28 which are suitably fixed to base 1l.

Angle irns 29 and 30 are suitably xed to the standard 16 or to any other fixed part of the machine to form a gauge adapted to locate a band l between the dies 27 and 28 in proper position to be severed and to have the severed ends thereof shaped as described above.

The operation of the machine will be obvious to persons skilled in the art from mere inspection of Figs. 6, 7 and 8 of the drawin s, and need not be further described herein.

ile I have described and shown the bands as having a central part lying between the plane of the contact edges of the band, the lnvention must not be considered as limited to this construction. It is immaterial whether the central part 4 be corru ated or plain; it is merely essential that it oes not lie in the plane of the edges 5 and 6, or in anyway to prevent contact of the edges 5 and 6 with the packing box surface. The nails will draw parts ofthe part 4 into contact with the packing box; but the parts between the nails and the outer edges of the bands will remain out of contact with the box.

I claim:

A flexible metal band for fastening boxes and the like having arcuate ends and a continuous bead extending along each edge and around the arcuate ends of said band, and in which the outer edge of the continuous bead is downturned to lie in a plane below the plane of that part of the band bounded by said continuous bead, the middle zone of the band within the bead being flat and yielding.

In testimony whereof I affix my signature.
